In a complex society, however, many contractual arrangements diverge so markedly from the classical model that they require separate treatment.
Furthermore, AR is estimated to be the youngest arrangement, diverging from ST 0.58 million years ago (Mya), but yet despite its age has reached high frequency in a relatively short time (95% confidence interval 0.51−0.65 Mya; Wallace et al. 2011).
reference was derived from specimens fixed for the standard arrangement (2L+ a/+ a), which is highly diverged from the inverted arrangement (2La) which is fixed in An. arabiensis (Cheng et al. 2012; Neafsey et al. 2010).
While most of these elements have diverged beyond a ∼2 Å r.m.s.d., their secondary structures, arrangement and structural implications are closely related.
Diverging living arrangements can explain most of the variation in the prevalence of jobless households across Europe.
Interestingly, this domain arrangement is also present in the Chlamydomonas genome, the green algae that diverged from land plants over 1 billion years ago.
Given the fact that chromosomes could consist of intervals of haplotypes that are highly diverged, endless breeding opportunities could be predicted, because of their linear arrangement along a chromosome and their expression potential in hybrid combinations [ 5, 14, 15].
Many of its members with contrasting rDNA arrangements (e.g. Tagetes v. Helianthus or the previously mentioned Elachanthemum v. Artemisia) probably diverged more recently.
In M. galloprovincialis, two mitochondrial DNA lineages (16,744 nt) have diverged by about 20% in nucleotide sequence but preserved identical gene content and arrangement [ 17].
In this regard, the mitochondrial gene arrangement of a distantly related animal, the phoronid Phoronis architecta [ 11], is very useful since it has little diverged since these groups separated.
